Which of the following is the chief role of Ozone Layer?  

The main role of the ozone layer is to absorb the majority of the Sun's harmful ultraviolet (UV) radiation. This protective layer, situated in the Earth's stratosphere, primarily contains ozone molecules (O3).

Key Points The ozone layer plays several crucial roles:

• UV Radiation Absorption: The ozone layer absorbs the majority of the Sun's biologically harmful ultraviolet (UV-B and UV-C) radiation.
• Protection of Life: By shielding the Earth from harmful UV radiation, the ozone layer provides essential protection for various forms of life, including plants, animals, and humans.
• Preservation of Ecosystems: UV radiation can harm aquatic ecosystems, affecting phytoplankton and other marine life.
• Climate Regulation: The ozone layer influences the distribution of solar energy in the Earth's atmosphere, playing a role in climate regulation
• Stratospheric Temperature Regulation: Ozone absorbs solar radiation in the stratosphere, contributing to the warming of this atmospheric layer.
